• 1 other identifier: GCO # 07-0332
• Study Type: interventional
• Target: 15
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to determine whether brain oxygenation measured by cerebral oximeter has an impact on neurocognitive dysfunction.

Conditions

Post-Operative Delirium; Postoperative Cognitive Dysfunction

Keywords

PD; POCD; Post-op Delirium (PD); Post-op Cognitive Dysfunction (POCD)

Outcome Measures

Primary Outcomes (1)

• The association of Postoperative Delirium (PD) and Postoperative Cognitive Dysfunction (POCD) with changes in cerebral tissue oxygen saturation (SctO2).

  First 5 days after the cardiac surgery.

Secondary Outcomes (1)

• Postoperative Morbidity and Mortality

  3 months postoperatively

Study Arms (2)

Cerebral Desaturation, i.e; SctO2 < 60 % for 5 minutes

ACTIVE COMPARATOR

Once the cerebral desaturation is established, the study personnel will attempt to optimize the level of oxygen within the brain of the study patients.

Procedure: SctO2 < 60 %.

Patients with SctO2 less than 60 %.

NO INTERVENTION

The study patients will not get any intervention in this arm if the Sct02 falls below 60%

Interventions

SctO2 < 60 %. PROCEDURE

The following intervention protocol will be applied when SctO2 level falls below 60 %. First, the patients head position will be checked for suitable position and the face will be observed for plethora. Then the efforts will be made to maintain PaCO2 between 40-50 mmHg and MAP of 60 - 80 mm Hg. Cardiac index will be maintained between 2.0 - 2.5 L/min/m2. The hematocrit should be more than 20 %. The red blood cells or hemoconcentration will be used for this purpose.

Cerebral Desaturation, i.e; SctO2 < 60 % for 5 minutes
